Title: Filter press with separate removal of suspended plates for cleaning - by two trolleys one for locking to stack other for separating one plate from stack
Inventor: BAUR ROLF ING GRAD
IPC: B01D25/172
Filed: 1980-07-08
Abstract: Filter press is composed of vertically hanging filter plates; each filter plate (1) is suspended by vertical arms (4,5) and slide blocks (7,8) from the two horizontal girders (2,3) along which all the plates can be moved, in order to dismantle them singly for cleaning. To segregate the filter plates one by one from the stack, a two- part trolley is used; the upper trolley (11) travels step by step from one filter plate to the next, while the lower trolley (12) is used for separating each plate in turn from the remainder of the stack and moving it into the discharge chamber; this lower trolley is equipped with an engaging mechanism (27) for towing the filter plate. Used for a filter stack where each filter plate in turn is removed to a discharge point where the cake is removed from it. By arranging two trolleys, the wt. of the mechanism is considerably reduced and smaller drive motors can consequently be used. In addition, cloth cleaning equipment or other auxiliary equipment may be mounted on the upper trolley.

Patent DE-3114788-A1 (DE)
Title: Energy-saving circuit of circulating pumps and burners in heating installations
Inventor: CLASEN-SCHULZ GEORG DIPL ING
IPC: F24D19/10
Filed: 1981-04-11
Abstract: The heating installations offered on the market, whether of conventional embodiment or in association with heat pumps, are, even for heating service water, designed in such a manner that the circulating pump (circulation pump) is in operation day and night. In the case of burner operation, heat which is not required is retained in the boiler also over night and at other times when the room temperature is lowered or no heat removal takes place otherwise. At these times also, current is consumed for the operation of the circulating pump and the cellar is heated pointlessly by the heat losses of the heating boiler. The aim of the invention is, when heat is not being removed, both to save current in the case of the circulating pump and to avoid the heat losses of the boiler by switching off the same. To this end, the operating current for the circulating pump is to be controlled by one or more relays and a controllable tubular contact or immersion thermostat in parallel connection. The burner is switched on or off via an additional relay with the aid of the operating current of the circulating pump.

Title: Process and plants for burning a coal-containing, ash-rich slurry
Inventor: WISCHNIEWSKI MARTIN
IPC: F23G7/00
Filed: 1981-06-27
Abstract: The coal-containing, ash-rich slurry, which is formed by wet separation of the fly dust produced in the gasification of coal, is dried in a pneumatic dryer (2). The dried material is ground and burnt in a dust furnace. Although the dust is extremely difficult to ignite because of its extremely low content of volatile constituents and because of its high ash content, it can surprisingly be burnt without additional fuel. The flue gases loaded with the total ash are used in part for drying the slurry, and in part for steam generation. The ash separated off downstream of the steam boiler has a residual coal content of less than 3% and is therefore usable as a raw material for the building materials industry.

Title: Diversity radio network
Inventor: DRIESNER JOERN MICHAEL DIPL IN
IPC: H04B7/022
Filed: 1982-03-20
Abstract: A diversity radio network is proposed in which a signal (M), comprising a lead time (V) and a following data telegram (D), transmitted from a mobile radio station (10) reaches a plurality of common-channel relay stations (12, 40, 41) simultaneously and in which it must be ensured that, even when a multiplicity of relay stations are involved which in each case successively transmit a quality signal, which evaluates reception quality, to a central radio station (5), no corruption of the data telegram (D) takes place. For this purpose, a memory device (21) is located in the AF-path between the receiving component (15) and, connected thereto, a control device (20) of each relay station. The memory device is dimensioned in such a way that a data telegram received in a relay station is stored for a specific time determined by the number of relay stations and is then forwarded via the control device to a transmitting component (34) of a feeder radio station (33). The data telegram then passes from the feeder radio station to the central radio station. <IMAGE>

Title: Lock for a divided backrest for the rear seats of a motor vehicle
Inventor: SCHAPER DIETER DIPL ING
IPC: B60N2/36
Filed: 1982-03-27
Abstract: A lock for a divided backrest for the rear seats of a motor vehicle whose backrest halves can be pivoted forwards individually and together about an axle which is located at the lower edge of the said halves and directed in the transverse direction of the vehicle has arranged on each side of the backrest on the inner wall of the body of the vehicle and to the sides of the backrest halves locks and latching elements which interact with one another and are manually actuable. In the dividing gap between the two backrest halves an additional locking device for releasably locking the two backrest halves with respect to one another is provided and the additional locking device can be actuated in each case simultaneously and together with one of the two lateral locking elements. In this way, a releasable connection between the two backrest halves is advantageously produced in their folded-back position in such a way that in the event of a head-on collision of the vehicle the load located behind the rear seat cannot pass through the gap between the two backrest parts into the passenger space and injure the vehicle occupants. The additional locking device does not in any way prevent the backrest halves being pivoted separately here since they can each be actuated together and at the same time with the respective lateral locking device for the backrest halves.

Title: Measuring device for measuring the flow velocity of liquids and gases
Inventor: HAAS LOTHAR
IPC: G01P5/10
Filed: 1982-05-18
Abstract: A measuring device (10) for measuring the flow velocity of liquids and gases in a piping system is proposed, which transmits via a thermal transmitter (12) thermal pulses which in the case of a flowing medium are detected by a thermal detector (13) and fed back electrically to the thermal transmitter (12). For this purpose, the thermal transmitter (12) is driven by an astable flip-flop (26) having a low fundamental frequency. Upon the occurrence of a measurement signal at the thermal detector (13), the flip-flop (26) is prematurely reset via a circuit arrangement (17, 23, 24) to the start of a new period. This feedback increases the frequency of the astable flip-flop (26) with increasing flow of velocity, and the signal frequency or the sum of the pulses for a specific time interval is output as the measured value on a display (37). <IMAGE>
